Can't edit overlapping polygons

Not sure if this is a solvable problem, but geojson.net suffers from the same problem as geojson.io, in that if one polygon is wholly within another, it can be impossible to click on in order to edit its properties.

Possible solutions:

• reorder the display to put smaller polygons on top (I think there are diabolical edge cases without solution, but they're probably very unlikely in practice)
• a special key modifier or something to ignore the first thing clicked on and "look deeper".
• a special key modifier or something that lets you click on a vertex (which always seem clickable) and use that as the way of accessing the polygon's properties.
• a meta tool to flip the order of everything. You could use that to flip, edit, flip when needed.
• a tool to send the selected layer "to the bottom", which would then let you edit layers that were obscured by it.

Maybe a selection tool that captures a rectangle and selects every feature within that rectangle. That together with a list of features that indicates which features are currently selected
